Application August 30, 194.8, SeralNo. 46,816

Our invention relates generally to improvements in roof structures for buildings, and more specifically to a metallic eave strip preferably of sheet metal, which while adapted for various purposes and uses, is especially designed for use in providing a finished cornice structure on a building, which joins or unites the roofing material ofthe building, to insure a durable, water tight and weather tight, and leak-proof' unionV of neat and workmanlike appearance.

The novel eave strip of our invention is adapted for use with various types of 'roofs built up of flexible layers or plies of roll or sheet roofing material, and the roofs may be finished with smooth surfaces as well asA with gravel surfaces; with the result that the metallic eave strip is permanently incorporated or embodied as a component part of the finished roof structure.

The eave structure includes a minimum number of parts that may with facility be manufactured at low cost of production, and the parts may be assembled and installed for use with a minimum expenditure of time and labor.

The invention consists in certain novel features of construction and combinations and arrangementof parts as will hereinafter be described and more particularly set forth in the appended claims.

In the accompanying drawings we have illustrated two complete examples of physical embodiments of our invention wherein the parts are combined and arranged. in accord with the principles of our invention. It will however, be understood that various changes and alterations are contemplated and may be made in these exemplifying drawings, within the scope of our claims, without departing from the principles of the invention.

Figure 1y is a vertical sectional view showing the eave strip of our invention embodied in a typical smooth surface roof. Figure 2 is a fragmentary perspective view in section showing` the eave strip structure; and Figure 3 is an end view sheathing. sine end ofv a refiera, and the face` 55.

'8 Claims. (Cl. 10S-26) cornice of a building structure.

In the preferred vform of the invention shown in Figs. 1, 2 and 3, we employ a sheet metal cornice structure, eave strip, or edging fashioned in.`

spaced to provide an exterior inverted groove,

channel or trough `5.

For attaching the sheetmetal strip to the wood face strip F, the front wall plate 2 may be punched with a series of nail holes as 6, or the holes may be punched by hand with a suitable tool, and after the angular strip is fitted over the cornice structure, the wall plate 2 is fastened to the face board as by nails N. These nails may'y also be utilized, as indicated in Fig. l, for attach-v ing a conventional gutter G to the front of the cornice structure, or frame board F. p

Before tting and fixing the eave strip in place,

``,the strip is equipped with one, or more, folded flexible fastening or anchoring strips or sheets,l

that are clamped and anchored within the inverted trough, as disclosed in Fig. 2. These strips may be fashioned. of felt, Water-proof fabric, or

other suitablematerial, and they are folded over an anchoring wire or rod 1, which clamps the bend of the strip at 3 -within the upper end of the inverted trough, leaving the edge flaps 9 and it hanging looselyA from the anchoring rod and 3 5 f trough.

The anchoring rod or wire spline 1 may be set V- within the eave strip in any suitable manner lto support the folded sheet or strip prior tothe merging of the flaps 9 and I n with the roof struc't ture; and the vertical abutting edges of the eave strips may be united by `a joint plate Il shown in Fig. 7. v

By means of headed rivets, as I2, passed transversely through the inverted trough, the anchor- Y ing strips are rigidly clamped between flanged and the front wall plate 2 with the flange 4- pressed and held in desired position against the. front wall plate, and leaving the iiaps 9 and. l0

in position to be upturned over the top surfaceof the cornice structure.

The roof flange l is fastened down on topof the sheathing S, as by nails N driven throughholes I3, and, together with the nails of the front Wall plate,` thel angular metalstrip is rigidly fastenedwith the closed,A upper. wal-l of? the-trough,-

strip or facia F usually employed at the eaves or y sheathing S.

The flap 9 of the folded sheet or strip is passed upwardly and around the trough, extended over and beyond the roof flange I, and laid in or built into the roofing structure, which is here shown as including three plies or layers I4, I5, and I6. The anchoring or joint flap III is also folded upwardly over the trough and laid between the second and third plies or layers of the sheet roofing material, and thus jointed to and embedded in the roong structure as a component part thereof.

The anchoring flaps and the plies or layers are cemented down and fixed in place by a coating of asphalt I1, or other similar coatings, in the usual manner for xing or laying the sheets or rolls of roofing material, to form the roof structure, and the joint or cave-edge of the roof structure is thus protected and anchored to insure a strong and durable Weather-tight and Watertight or water-proof roofing.

The end of one of the lengths of edge strip may be slightly splayed to receive the ends of the plies of fabric and telescoped into the plies of fabric of the adjoining length of edging, and at this point there would be four plies of fabric at the lap above the joint plate I I.

The number of anchoring strips 9, I0, of the water-proof fabric may be changed and determined by the number of plies or layers of the roof structure, and the number of plies of sheet roofing vmaterial is determined by the desired life or durability and type of the roof structure. As thus anchored, should the roof buckle, the eaveedge of the roof remains fixed and is proof against leaks; and the roof is tied down so that the wind cannot get under the cave-portion to lift the roof.

In Figs. 5 and 6 where a front wall or guard is provided for a gravel surface roof made up of layers or plies of sheets or rolls, the roof flange I and the front Wall plate 2 are fashioned with an inner double-thick flange I8 that forms an inverted trough I8 above the roof flange. The anchoring wire or spline 1, within the trough clamps the water-proof fabric or anchoring strip so that its flap I is laid and cemented down over the roof flange I, and extends between the edges of the plies I4 and I5, while the flap 9 is fixed between the roofing layers or plies I and I6. The joint plate II in this form of the invention is provided with a hooked end or upper rounded flange I la that lits over the inverted trough, and the plate is fastened by nails with the front wall plate to the front face board F.

By means of the anchoring flaps, the plies or layers of the roof are rigidly anchored and cemented together with asphalt, as II, or by the use of other suitable compositions or materials; and the gravel surface 20, embedded in tar, asphalt, or other cementing composition, provides a cover for the roof that is guarded by the use of the inverted trough. The water proof and weather proof guard or cornice rail thus affords a leak proof finish of workmanlike and artistic appearance for the eaves portion of a roof, and the roofing material is conned and retained at all sides of edges, by the guards against displacement.

Having thus fully described our invention, what we claim as new and desire to secure by Letters Patent is:
